Adding & Subtracting Fractions

NOTE: If you are going to PRINT the mini-lesson handouts, be sure to set your browser's FILE > PAGE SETUP for 0.5 inch margins and portrait orientation. Some cells have background color -- this color will only print if you turn on printing of background colors and images (TOOLS > INTERNET OPTIONS > ADVANCED TAB > PRINTING).
NOTE: If you would like to PRINT a single screen from the mini-movies, you can right-click on the screen (as the movie is playing or pause the movie). Select PRINT from the menu and the full movie window will print.

 What are the Mini-movies?

What are the mini-movies? The mini-movies are marked with a icon. They are are flash video files that contain a teaching presentation with an audio track. These were recorded in my office (not lecture) so they are short, but very dense (crammed full of information). Movie controls are available so you can replay, pause, and skip sections.
